In this paper, a study of the behavior of the CIE L*a*b* color space to detect subtle changes of saturation during image segmentation is presented. It was performed a comparative study of some basic segmentation techniques implemented in the L*a*b*, RGB color space and in a modified HSI color space using a recently published adaptive color similari...

In recent years considerable effort has been devoted to the problem of color segmentation in digital images given its importance and potential. Until recently, most published approaches for color segmentation were based on monochromatic techniques applied to each color component of the image in different color spaces (RGB or other) and in different...

In this article, we present an adaptive color similarity function defined in a modified hue-saturation-intensity color space, which can be used directly as a metric to obtain pixel-wise segmentation of color images among other applications. The color information of every pixel is integrated as a unit by an adaptive similarity function thus avoiding...

In this paper an evaluation of the influence of luminance L* at the L*a*b* color space during color segmentation is presented. A comparative study is made between the behavior of segmentation in color images using only the Euclidean metric of a* and b* and an adaptive color similarity function defined as a product of Gaussian functions in a modifie...

In this paper a study of the influence of luminance L* at the CIE L* a* b* color space during color segmentation in highly saturated color images is presented. A comparative study is made between the behavior of segmentation in color images using (1) the Euclidean metric of the RGB channels (2) the Euclidean metric of a* and b* in CIE L*a*b* color...

In this paper a study of the influence of luminance L* at the L* a* b* color space during color segmentation is presented. The behavior of different color image segmentation algorithms is studied, in particular, the techniques based on only the Euclidean metric of a* and b* and an adaptive color similarity function defined as a product of Gaussian...

We present an evaluation and limited characterization of an own semi-automatic color image segmentation method using generated synthetic images with its associated ground truth. The synthetic images where designed to evaluate the efficiency of the resulting color information achieved from color segmentation algorithms. By the use of ROC curves and...

We present an interactive, semiautomatic image segmentation method that processes the color information of each pixel as a unit, thus avoiding color information scattering. The color information of every pixel is integrated in the segmented image by an adaptive color similarity function designed for direct color comparisons. The border between the...

In this paper an interactive, semiautomatic image segmentation method is presented which, processes the color information of each pixel as a unit, thus avoiding color information scattering. The process has only two steps: 1) The manual selection of few sample pixels of the color to be segmented in the image; and 2) The automatic generation of the...

Abstract. An interactive, semiautomatic image segmentation method is presented which, unlike most of the existing methods in the published literature, processes the color information of each pixel as a unit, thus avoiding color information scattering. The process has two steps: 1) The manual selection of few sample pixels of the color to be segment...

An interactive and semiautomatic image segmentation method is presented which, unlike most of the existing methods in the published literature, uses the color information of each pixel as a unit, thus avoiding color information scattering. The color information of every pixel is integrated by an adap-tive color similarity function designed for dire...
